FIELD OF TECHNOLOGY

This invention concerns electronic technology.

TECHNOLOGY BACKGROUND

The batteries which can show their residual volume in today's market, such as Duracell (trade mark), they have a liquid crystal linking positive and negative poles, which is between the surface of battery and its casing. The residual volume is showed in the liquid crystal; however, liquid crystal hasn't lighting function, so customers cannot watch the residual volume in dark environment.

China patent 200720032012 publishes a new battery. It can not only provide power but also shine itself. There is a light-emitting diode linking the battery's positive pole and negative pole. And light-emitting diode is incorporated with battery. The disadvantage of this patent is that it will cause power volume decreasing if we don't change the battery's size, because incorporating light-emitting diode and battery will cause the light-emitting diode occupying the inner space of battery. The production craft of battery is different and cannot contain the same power as before.

China patent 200610114507.5 publics a lighting battery which can be charged. Its major part is light, and there is a larger different from common battery.

INVENTION CONTENT

The technology issue should be solved in this invention is to provide a new type of battery, achieving the aim that the battery can not only shine itself, but also show its residual volume in dark.

There are two ways to design lighting battery. The first way is that film light-emitting diode can be set up in the surface of battery, contacting positive and negative poles. Besides, a micro-light-emitting diode also can be set in the end of battery, linking positive pole and negative pole through lead.

The above-mentioned film light-emitting diode is in the flank of battery, covered by the casing. And the casing covering the film light-emitting diode is transparent. Or a micro-light-emitting diode can be set in the end of battery.

A driving circuit linking with light-emitting diode is fixed in battery's surface. There is a switch being set in the circuit which links with light-emitting diode and battery's positive and negative poles. The stitch is filmy osculant switch. And this switch is an elasticity osculant switch, it is normally opening. The driving circuit and light-emitting diode are set around the top of the battery, or being set in the bottom of the battery.

The above-mentioned batteries can be D, C, AA, AAA size, it also can be 3V, 6V, 9V batteries.

There are several advantages of this invention. First, because the film light-emitting diode is fixed in the surface of battery, we don't need to modify a lot in existing battery product line. Therefore, we can achieve a new function in the lowest cost. Second, the battery equips luminescence light-emitting diode, so it has lighting function instead of a electric torch. It can provide a large convenience when suffering earthquake or other emergency situation. Third, the battery has a long using life due to the high energy conversion efficiency. Besides, setting an elasticity film switch in light-emitting diode can control the lighting time of light-emitting diode. Furthermore, this invention can show the rest volume of power, which is convenient to make full use of battery and good for environmental protection.

This invention makes an improvement of battery, and the new adding function will not affect the power supply functions which battery using in other electric apparatus. This is an important difference between the new invention and existing light-emitting diode technology.

A further illustration is explained with attached drawing and idiographic implemental approaches as follow.

This invention sets up a flim light-emitting diode 12 in battery's surface, flim light-emitting diode 12 links with batteries positive and negative poles through conductor 3, light-emitting diode is supplied power from battery; there is a film elasticity switch setting in the power supply circuit of light-emitting diode. Elasticity switch is consisted with lead 3 and insulator 4 which has small holes. It is normally opening. Lead 3 link with battery's negative pole through when giving outside force and light-emitting diode will light; light-emitting diode is between the battery casing 5 and battery main body.

Implemental Example 2: See also FIG. 2

Light-emitting diode is fixed in battery's top or bottom. The top of battery is positive pole, the bottom of battery is negative pole, so the light direction of light-emitting diode can accord mainly battery's axes direction to be used convenient.

Considering some light-emitting diode's lighting voltage are higher than 1.5V, however, the common family battery, namely, D, C, AA, AAA, their voltages are around 1.5V. To be an improvement, a driving circuit is set in the top of battery, and linking with light-emitting diode, using to complete voltage exchange between common family batteries' 1.5V and light-emitting diode's voltage.
